The document describes the NFC SmartTool, an open-source NFC development kit. It consists of three separate boards that together provide an NFC reader and antenna, LCD display, microcontroller, and optional Bluetooth/WiFi modules. The kit includes fully documented hardware schematics, PCB layouts, and source code for embedded and Android software. It is intended to allow developers to easily create NFC-enabled prototypes and applications for access control, payment, and device communication.
